VISE.

Specification of Letters Patent.

Patented Nov. 28, 1911.

To all whom it may concern:

Be it known that I, VViLLIA M ANDREW HYLE, a citizen of the UnitedStates, and resident of Buffalo, in the county of Erie and State of NewYork, have invented new and useful Improvements in Vises, of which thefollowing is a specification.

This invention relates to a vise which is used more particularly forholding pipes but which may also be used for other purposes.

One of the objects of this invention is the provision of simple andefficient means whereby the principal part of the adjustment of the visemay be effected quickly and only the final tightening effected slowly.

This invention has the further object to render the movement of theparts while opening and closing the vise easy and to so construct theparts that the vise is very strong, that worn parts can be realilyreplaced and the vise can be produced at low cost.

In the accompanying drawings consisting of 2 sheets: Figure 1 is ahorizontal section in line 11, Fig. 2. Fig. 2 is an end elevation of thevise. Fig. 3 is a vertical longitudinal section in line 33, Fig. 1.Figs. 4, 5 and 6 are vertical transverse sections in the correspondinglynumbered lines in Fig. 8.

Similar letters of reference indicate corresponding parts throughout theseveral views.

A represents the base of the vise which may be secured to a work benchor other support in any suitable manner. At its front and rear ends thisbase is provided with two upright front and rear standards or posts B, Cwhich are fixed on the base and preferably cast integrally therewith.Between the two standards the base is provided with a longitudinal slotD which is undercut so as to form downwardly facing shoulders 03, d onopposite sides of the slot, as shown in Figs. 3, 4 and 6. To the rearstandard are secured the two widely separated sections E, E of a rearfixed gripping jaw which are adapted to engage with the rear side of thepipe and widely separated points and which are detachably secured toopposite sides of the rear standard by bolts 6, as shown, or by anyother suitable means. Arranged in front of the space between the rearfixed. jaw sections are two narrowly spaced sections F, F of a frontmovable gripping jaw which are adapted to bear against the front side ofthe pipe at two points arranged comparatively close together and out ofline with the bearing points of the rear jaw sections. It will thus benoted that the pipe by this means is gripped at four different placeswhereby the same is positively held against turning while a thread isbeing cut on the same or other work is being performed thereon whichrequires the pipe to be held firmly.

The front jaw sections are secured by bolts 9 or otherwise to oppositesides of an upright longitudinally movable slide G which projects at itslower end downwardly through the guide slot D and moves lengthwisetherein for opening and closing the vise. The lower ends of the frontjaw sections are arranged above the base on opposite sides of the slot Dand thereby prevent downward movement of the front jaw and slide. Upwardmovement of these parts is prevented by a cross head it arranged at thelower end of the slide G and engaging at its opposite ends with theshoulders 03, a? of the slot D.

In order to cause the front aw and slide to move freely withoutliability of becoming cramped or bound, rolling members or bearings areinterposed between the lower ends of the front aw sections and the base.These rolling members preferably consist of a plurality of balls 2'arranged in recesses 71 in the lower ends of the front jaw-sections andengaging with longitudinal rim ways on the upper side of the base onopposite sides of the slot D, as shown in Figs. 2 and 6.

The forward and backward movement of the front jaw and slide relativelyto the rear jaw may be effected by various means but preferably ahorizontal screw J which is operatively connected at its front end withthe front jaw and slide and works in a screw nut in the front standard.The preferred means for connecting the screw with the slide and frontjaw comprises a spherical knuckle L connected with the rear end of thescrew by a contracted neck Z and seated in a spherical socket in theslide and front jaw sections. As shown, this socket is formed by meansof a notch arranged in the front edge of the slide and consisting of anarrow or contracted outer part m and an enlarged inner part m and twoconcave recesses 12, formed on the inner sides of the front jaw sectionsin line with the enlarged inner part m of said notch.

In the assembled condition of the parts the neck Z of the screw isarranged in the contracted part m of the notch and the spherical knuckleengages centrally between its laterally opposite sides with the enlargedpart m of the notch while its opposite sides engage with the recesses nof the-front jaw sections, thereby forming a swiveling connectionbetween the screw and movable jaws which permits of freely adjusting thelatter without liability of binding and still keeping the cost ofmanufacture and the capacity of being repaired within practical bounds.

At its front end the screw is provided with a handle 0 for turning thesame which handle may be of any suitable construction, the same beingshown in the drawings,for example, in the form of a cross bar.

In its preferred form the adjusting screw nut which cooperates with thescrew, as shown in Figs. 1 2, 3 and 5, is constructed of two cylindricalsections p, p which are arranged in a cylindrical socket P in the frontstandard and which have their opposing ends constructed to form anopening which is internally threaded and in line with openings 9, q inthe front standard on opposite sides of the screw nut. The adjustingscrew passes through the adjusting nut and the adjacent openings 9 ofthe front standard. Upon turning the screw in one direction or the otherwhile the nut sections are both engaged therewith the front jaw will beslowly moved toward or from the rear jaw accordingly. W'hen it isdesired to move the front jaw quickly toward or from the rear jaw thesections of the adjusting nut are separated and the adjusting screw isdisengaged therefrom, thereby permitting the adjusting screw to be movedlengthwise through the adjusting nut without turning the same and thusenabling the main part of the adjustment of the vise to be effectedrapidly. After the parts have been shifted approximately into theposition for gripping a pipe the sections of the adjusting nut and theadjusting screw are again engaged and the final tightening of the jawsagainst the pipe is eflected by turning the adjusting screw in the screwnut. By this means the operation of adjusting the vise pipes ismaterially facilitated and cost of doing the work reduced accordingly.

The lower adjusting screw nut section 79 is preferably secured in thefront standard by a transverse pin 1- and the upper section p is movablevertically toward and from the lower section but is held againstturning.

by means of a pin 8 projecting laterally from the upper nut sectionthrough a vertical slot 8 in one side of the front standard. At itsupper end the upper nut section is provided with a handle or knob s formanipulating the same.

Various means may be employed for holding the upper section p in itsoperative or inoperative position, the means for this purpose shown inthe drawings consisting of a leaf-shaped locking spring T secured at oneend to the outer side of the front standard and provided at its otherend with two openings 2 t which are adapted to receive the pin s of theupper nut section. When the upper nut section is depressed into itsoperative position the pin 8 engages with the lower opening I? of thelocking spring T, thereby holding the adjusting screw nut sections andscrew in engagement with each other. Upon raising the upper screw nutsection and engaging its pin .9 with the upper opening t of the lockingspring this nut section will be held in its inoperative position.

By splitting the screw nut the same may be separated and the adjustingscrew detached. therefrom and the movable jaw quickly shifted while thefine adjustment and tightening of the jaws is effected when theadjusting screw is engaged by the screw nut sections. The adjustingscrew can be readily lifted out of engagement from the lower fixedsection of the screw nut owing to the pivotal connection between thisscrew and the slide which carries the movable jaw.

The screw nut sections p, p are con structed from a cylindrical blockwhich is first bored transversely, then internally threaded in this boreand then divided transversely through this bore. The opening or socket Pin the standard B is of the same diameter as the screw nut sections p, pso thatthe latter fit snugly in this socket. This manner of constructingthe screw nut sections and mounting the same in the standard B is verysimple, reliable and eflicient and can be produced at low cost.
